Owners who have experienced the issue said they are unable to start their vehicles after charging, according to The Verge , which first reported the issue on Thursday.

Ford said only “a small number” of Mach-Es built before February 3 were affected, and dealers are able to correct the issue by reprogramming several of the electronic control modules on the vehicle.

Ford said it sold 6,614 Mach-Es in the first quarter. Tesla, the industry’s electric vehicle leader, said it delivered a record 184,800 cars worldwide in the quarter.
